Eosinophilic gastroenteritis (EGE) is a rare chronic inflammatory disorder characterized by infiltration of different parts of the gastrointestinal (GI) tract with eosinophils producing variable clinical presentations.

Diagnosis is largely dependent on the histopathological findings in the appropriate clinical context and absence of other causes of eosinophilic infiltration such as inflammatory bowel diseases, parasitic infections, drugs and malignancies.

The mainstay of treatment is systemic steroid. However, several other immunomodulatory agents have been used as a second line therapy.

Omalizumab is an anti-IgE monoclonal antibody developed for treatment of severe uncontrolled bronchial asthma and urticarial, its’ efficacious utilization for treatment of EGE has been reported recently in the literature.

Herein, we report a case of 25-years-old male patient who presented with acute abdomen requiring surgery and bowel resection, he was found to have eosinophilic infiltration of the GI tract on subsequent workup, Other secondary causes of eosinophilic infiltration were ruled out.

A trial of Omalizumab was initiated after a long-term therapy of systemic steroids and multiple relapses of his abdominal pain upon tapering down his steroids dose, therapy with Omalizumab has resulted in a remarkable clinical response and sustained remission of his symptoms.
